DEVICE FOR WITHDRAWING LIQUID FROM CONTAINERS.

To all whom it may concern: Be it known that I, GEORGE W. LAKE, a

citizen of the United States, and resident of the town of Rumford, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Devices for Withdrawing Liquid from Containers, of which the following is a specification.

This invention relates to devices for withdrawing liquid from a container by a siarticularly adapted for use in drawing 0 the top ofmilk from a bottle, one leg of which is adapted to extend into the bottle and to provide simple and eifective means for starting the flow of the liquid contents outward through the tube.

A further object of this invention is to provide simple and effective means whereby the U-tube may be adjusted vertically so as to regulate the depth to which the inwardly extending leg shall project into the bottle to control the amount which shall be drawn therefrom.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a view partly in section showing the U-tube in position for withdrawing the top of the milk from a bottle; also representing the thumb of theoperator as closing the valve-opening and slmultaneously depressing the bendable disk to create an internal pressure and start the flow outward through the tube.

Fig. 2 is a detail of the U-tube representing itstwo legs as being of dllferent lengths.

Fig. 3- is a perspective view of the diskshaped bendable stopper showing the tube hole and the valve hole therethrough.

Fig. 4 is an edge view of the stopper disk showing the periphery as beveled whlch causes it to take a convex shape when positioned in the bottle.

Fig. 5 shows the disk as ccnvexed in the neck of the bottle.

My invention comprises primarily a U- shaped tube 10 which is preferably made of glass, the same being bent at 11 to extend Specification of Letters Patent.

overthe upper edge of the bottle neck and providing one short leg 12 to project down 1nto the bottle neck and one longer leg 13 to extend down on the outside of the bottle below the end of the shorter leg. A bendable disk-shaped member 14 which may be made of rubber, leather, celluloid, thin metal or other suitable bendable material, is formed of a size to fit tightly into the neck of a bottle and is provided with a hole 15 near its periphery through which the shorter leg of the tube extends. This disk is also provlded with a smaller hole 16 near its center, to serve as a valve as presently described.

It is almost the universal custom in certainsections of the country to deliver milk in glass jars or bottles through whichthe depth of the separated cream can be readily observed in theneck or top thereof, and it is found quite diilicult to pour off this creamy portion without stirring u and taking with it some portion of the thiy er milk.

To obviate this difliculty I have provided an extremely simple, practical, elfective and sanitary device for withdrawing the exact amount desired from this bottle, to accom-' the bottle, which causes the contents to rise in the tube over the bend and run down the longer leg 13 into the receptacle 17. The thumb is now withdrawn from the valve opening permitting the air to enter and the siphonic action in the tube causes all of the cream above the lower end 18 of the tube to run out. The discharge may be arrested at any time by simply placing a finger over the valve opening, which will again continue when the finger is removed. When the contents have been drawn down to the lower end of the tube the liquid will automatically cease to run.

One of the features of this simple device is that the tube may be readily adjusted vertically through the disk stopper so that its lower end may beipositioned at the mark of separation between the milk and the cream at whatever height that may be.

' Another feature of this invention is that I susceptible, the invention being defined and bevel the edge 18 of the disk whereby when it is placed in the bottle with its greatest diameter downward it will naturally stand in a convex position, as best illustrated in Fig. 5, so that a slight pressure on its surface will force it from this convex to the concave position as illustrated in Fig. 1, which action is sure to create suflicient pressure within the bokt)tle to force the contents out through the tu e.

I have shown and described my improved device as being applied to a milk bottle for withdrawing the top of its contents, but this device may be used for any purpose for which it mav be adapted. .I have also shown and described the stopper as being set into a groove within the neck of the bottle, but my lnvention is designed to cover a disk or other form of cap held in any way on the receptacle whereby a depression of the same creates a pressure within the bottle to force its contents outward through the tube. I reserve the privilege of resorting to all the mechanical changes to which the device is claims.

I claim:

1. A siphon device comprising a thin resilient disk having its edge shaped to fit air tight in the internal annular groove in the neck of a milk bottle, said disk being provided with a vent hole nearits center and a tube hole near its edge, and a U-tube having one leg adjustably held in said tube hole to extend into the bottle.

2. A siphon device comprising a concavolimited only by the terms of the appended convex disk having a thin beveled edge to fit tight in the internal annular recess in the neckof a milk bottle, said disk being provided with a vent hole near its middle portionand atube hole near its'edge, and a U tube having one le adjustably held in said tube hole to exten into the bottle.

In'testimony whereof I aifix my signature in presence of a witness. GEORGE W. LAKE.
